For sure we don't have any pop-ups and hidden agreements.
Something popped up. And it had a tick box anf the fedora(?) icon.
I didn't have time to read any of the text before the successfully installed pop-up removed it. The pop-ups happened in this order:
[Do you want to install?]→Installing…→[???]→[successfully installed.]
The first and last pop-ups remain until I click confirm or cancel, the second remains until the progress bar fills up, or installation fails.
Those are the only three pop-ups I've had to deal with on a successful installation.
But this time, there was a fourth one ([???]) that was only up long enough to register it's existance and a handful of details about it.
I didn't have time to read the text, though I think some of it was coloured, though it may have been smaller images. I was able to identify a tick box. There may have been bottons, I don't know, it vanished too quickly.
Since you say you don't have pop-ups, it must be something by Android or Samsung's developers, which complicates things. I was hoping you might have seen or heard of this and had some idea why it happens… Now I highly doubt I'll ever solve this…
Thank you for your response non the less.
I only have the one device… and reinstalling it (update method) did not have it come up.
I haven't done much. Did the maze once, and gathered berries.
It's impossible to reach the pickaxe.
So, I'll uninstall and reinstall. •If it pops up again,• I'll try to screenshot it. Since if it does pop-up on reinstall after uninstall, I •theoretically• have infinite tries to attempt screenshotting it during the brief moment it's on screen.
Dunno how long this will take.
